ipq40xx: remove support for kernel 4.19

The target uses 5.4 as default kernel since 03/2020.

Kernel 4.19 support is not really maintained anymore, it does not
seem to be needed, and removing it will make upcoming driver
updates easier. Thus, remove it.

-Subject: [PATCH 2/3] phy: qcom-ipq4019-usb: add driver for QCOM/IPQ4019
-
-Add a driver to setup the USB phy on Qualcom Dakota SoCs.
-The driver sets up HS and SS phys. In case of HS some magic values need to
-be written to magic offsets. These were taken from the SDK driver.
